The results show that the energy consumption under single layer glass curtain walls is generally higher than thatunder double-layer glass curtain wals.In comparison，theannual static energy consumption is about 29 % higher， the winter static energy consumption is about 22% higher，and the summer static energy consumption is about 24% higher.The energy-saving efctffoat glasscurtainwallisthebstinsingle-layerglasscurtainwalls，andthecorespondingdoubl-lar glass curtain wall with a combination of float glass and float glass has the best energy-saving effect.

我國建筑業(yè)正逐漸向著智能化、綠色化方向發(fā)展，高能耗建筑在建筑工程中的比例也在逐漸增加，玻璃幕墻是目前高層建筑常采用的圍護結(jié)構(gòu)之一，其獨特的建筑美學(xué)效果使其被廣泛應(yīng)用，但大面積玻璃幕墻增加了建筑的能耗，在倡導(dǎo)建筑節(jié)能的新時代下，針對不同類型玻璃幕墻對高層建筑能耗影響分析具有極其重要的意義。（剩余5000字）
